HVH SS4150-.5AL Super Sucker 604 Carburetor 4-Hole Spacer,1/2 In.
604 GM Chevy Crate Engine, 0.5" Overall Thickness, Aluminum, 4-Hole Carburetor Spacer Style
Designed by Joe Petelle at HVH over 15 years ago for Winston Cup engines, this spacer will increase air speed from the base of the carburetor to the top of the intake valve, pulling more fuel from the carburetor, the Super Sucker will require a change in the size jet currently being used. E.T. is reduced as much as 1/10 of a second and lap times reduced as much as 2/10 of a second.
Improvements in the throttle response, driveability, top end horsepower and torque are commonplace when using a Super Sucker.
This 1/2" aluminum spacer is specifically designed for the 604 crate engine and gives more low end and mid range torque without reducing top end torque.
